What is DynaFit?

DynaFit

DynaFit is a handy application designed to help with nonlinear least-squares regression. It’s perfect for crunching numbers related to chemical kinetics, enzyme kinetics, or ligand-receptor binding data. So, if you have experimental data like initial reaction velocities based on different concentrations (think inhibitor concentration vs. velocity), or maybe reaction progress curves (like time vs. absorbance), this tool has got your back!

Key Features of DynaFit

The coolest thing about using DynaFit is how it helps you describe your (bio)chemical system using symbolic or stoichiometric equations. For instance, if you're dealing with a slow, tight inhibition of a dissociative dimeric enzyme, here's how it might look:

Monomer + Monomer → Enzyme     :  k1  k2

Enzyme + Inhibitor → Complex   :  k3  k4

Enzyme + Substrate → ReactiveX :  k5  k6

ReactiveX → Product + Enzyme    :  k7  k8

The names used for chemical species like “Monomer” and “Enzyme” can be whatever you want! You’re free to choose names that make sense for your work.

Getting Started with DynaFit

Once you download DynaFit, you’ll find that it's ready to process around 200 example data files right off the bat! These examples are part of about 50 included problems that can really help you get the hang of things.
